The following steps build the project locally
First we need to create a .env file at the root of the project directory since it is used to add the a mnemonic and infura key to the project for deployment on a network. Add them as:
MNEMONIC=<Your mnemonic string>
PROJECT_ID=<Your Project ID from Infura to deploy on a public network>
Use the mnemonic saved in .env or any other based on your requirement
ganache-cli -m "<your mnemonic>"
truffle compile
Deploys locally
truffle migrate
Run Tests
truffle test
Since there isn't a sign up mechanism for users to register themselves in a particular role (like Farmer, Distributor, Retiler or Consumer), we're going to add addreses manually.
Enter the truffle console with
truffle console
Now inside the console, use
let contract = await SupplyChain.deployed()
This will save a reference to the deployed instance of the contract. Now we can proceed with adding addresses to various roles manually, like this -
contract.addFarmer(address[1])
contract.addDistributor(address[2])
contract.addRetailer(address[3])
contract.addConsumer(address[4])
Entering these commands will produce outputs to the console similar to
cd client
npm start
In order to use the Dapp with the various configured roles, we will need to add the accounts to Metamask manually.
